Yeah, it's kind of a monster isn't it? If you put the 2nd fan opposite the memory it might work, but no promises. It's still heavy which always bugs me too, so...how about it's predecessor NH-U12P SE2
which is smaller and performs very close to the NH-D14? I think the fans on the 14 are superior to the older 12's (by 10CFM and same dB), but the results of the two are so close that in the end it may not really matter.
There's also the much more affordable Coolermaster 212 Evo
and the newer 612
that are still very respectable for the dollar. They're not pretty to look at, but they both function very well.
